Hello all
Here you will find what I need
---------------------------------------------
Name Region No_Customers No_Names
---------------------------------------------
Albert US 12 3
Albert FR 91 3
Albert EC 2 3
Cecilia US 3 4
Cecilia CA 4 4
Cecilia CH 34 4
Cecilia FR 12 4
Martha EC 9 1
Rodrigo CO 2 1
---------------------------------------------
Where Name is the sales representative
Where Region is the country
Where No_Customers is the number of customers in each country
Where No_Names [must be] the number of times a Name appears in the column Name
Te table [Data] has this structure:
ID, Name,Region.
The goal is to create a column with the number of times that a name is repeated in the Name column.
e.g. Cecilia appears 4 fours because her name is in 4 regions.
Albert apeears 3 times so it shows 3 in No_names
I hope I was clear with my output example.

Using Vinu's sample, here is a shorter query, which uses SQL 2005
syntax:
select id, name, region, cnt = COUNT(*) OVER (PARTITION BY name)
FROM #t
ORDER BY name
COUNT OVER does not always give good performance, though.
